Broadly ETL developer would be basically understanding the data model, designing the model for EDW, mapping the data and running the ETL jobs.

An ETL developer (depending on the level of experience or position in the project) in a company can perform one or more of the following tasks: Developing ETL mappings / pipelines for integrating data to / from sources such as DBMS (SQL Server / Oracle / MySQL / PostgreSQL / Access) / CRM (Salesforce) / Websites via API / Flat Files (CSV / XLSX / XLS / XML / JSON) / No SQL Databases (MongoDB) / Column Database (AWS Redshift), Application Integration (Workday / Anaplan) , Data Modeling with Tools like ERWIN or Toolless, Database Administration, ETL Tool Administration (Informatica / Snaplogic). By the way, you can read more in the article All About an ETL Developer - Responsibilities, Goals & Tech Arsenal https://idapgroup.com/blog/who-is-etl-developer/  and draw your own conclusions

For a long time I have been looking for a place where you can invest money, but in the end I settled on the idea of ​​creating my own business for an IT company. Everything went well at first. But in the end there was a problem with the staff. I needed a very advanced developer. I could find it on this site hire a dedicated php developer . I was able to find such a professional thanks to a large base of employees, which includes more than 400 thousand employees from all over the world. Also on the site you will be helped to understand all the intricacies of IT developments. I can’t say anything, except how to advise!
